(Reuters) - When supermodel Heidi Klum decided to write a book, she didn't want it to be just a picture book. She wanted to offer some words of wisdom.

Of course the book, "Heidi Klum's body of knowledge," does have pictures -- 400 of them to be precise, including a number of nude shots and plenty of the German temptress clad in the underwear brand that launched her on the way to super-stardom.

But that's not the point of the book.

Among eight "rules of model behaviour" Klum outlines are such maxims as "You have to want it, baby" and "Have a blast while it lasts." And there are tips on getting ahead at work and getting better sex -- Heidi's advice: "Become the fantasy."

"I wanted to write something because I thought I had so many great stories to tell and I had so many pictures and I didn't want to just do a picture book," Klum said after signing copies at a Wall Street bookshop in New York on Friday.

"It's for guys who want to know more about girls and for girls who want to know more about guys," she says, adding that she sees it as her equivalent of a greatest hits album.

Klum has enlisted a host of famous friends to share their favourite pearls of wisdom -- among them Donald Trump on how not to let criticism beat you down and Miramax movie mogul Harvey Weinstein on how to break into show business. And just to prove that she's a normal girl, Klum admits in the introduction of the book that she pigs out and gets pimples like anybody else. "In fact, thanks to my adolescent acne, some snotty kids in high school used to call me Pizza Face."
